PMID: 33612819

Despite the medical, veterinary and forensic relevance of myiasis-causing flies, knowledge of their diversity in Saudi Arabia is limited especially in the southern region. Therefore, a survey of myiasis-causing flies in the Jazan region was carried out using Red Top Fly Catcher traps baited with either decomposing beef liver or a lure composed primarily from fishmeal during the period April 2013-March 2014. Twelve known species were identified and recorded in this study, seven species of them belonging to Calliphoridae (Chrysomya, Lucilia, and Hemipyrella) and five species belonging to Sarcophagidae (Sarcophaga). Two of these species were recorded for the first time for Saudi Arabia, namely Hemipyrella pulchra (Wiedemann, 1830) and Sarcophaga (Liosarcophaga) exuberans Pandellé, 1896. Images of the species recorded are also provided for the first time. The results expand the knowledge of geographical distribution, fauna, and habitat of the myiasis-causing flies in Saudi Arabia. Biological information and world-wide geographical distribution of these species are included together with some taxonomic remarks.

Ramalingam S, Nurulhuda A, Bee LH

Southeast Asian J Trop Med Public Health, 1980 Sep;11(3):405-7.

PMID: 7444582

A case of urogenital myiasis caused by Chrysomya bezziana (Diptera: Calliphoridae) was diagnosed in a 76-year old patient who had carcinoma of the rectum. A total of 35 larvae were obtained from ulcers near the external genitalia and urethra opening. Larvae pupated within 1 to 2 days and 6 days later emerged as adult males. These were identified as Chrysomya bezziana. Female flies possibly attracted by the fetid odour, laid eggs in the existing lesions in the urogenital area, the larvae invading and feeding on living tissue. Lack of personal hygiene was the contributing factor for the cause of urogenital myiasis in this patient.

Chrysomya bezziana (Diptera: Calliphoridae) infestation: case report of three dogs in Malaysia treated with spinosad/milbemycin

Han HS, Sharma R, Jeffery J, Noli C

Vet Dermatol, 2017 Apr;28(2):239-e62.

PMID: 27918123 DOI: 10.1111/vde.12403

BACKGROUND: Infestation of wounds with the larvae of Callophorid flies is relatively common in countries where these parasites are found. The most common species associated with infections in Southeast Asia is Chrysomya bezziana (Ch. bezziana), the Old World screw worm. Treatment consists of either subcutaneous injection of ivermectin or oral administration of nitenpyram combined with aggressive tissue debridement under general anaesthesia.

OBJECTIVES: To describe the treatment of cutaneous myiasis in three dogs caused by the larvae of Ch. bezziana in Malaysia and their treatment with spinosad plus milbemycin.

RESULTS: In all dogs, a single oral dose of spinosad plus milbemycin at the recommended dosage of 31-62 mg/kg and 0.5-1.0 mg/kg, respectively, was able to kill all larvae within 8 h. Most dead larvae fell off the host and those remaining on the host were dead and easily removed with simple saline flushing and gentle debridement. Neither general anaesthesia nor aggressive mechanical debridement were needed in any patient.

CONCLUSIONS AND CLINICAL IMPORTANCE: Oral spinosad plus milbemycin is a safe, licensed and effective treatment at the recommended dose for the rapid elimination of Ch. bezziana myiasis, with no need for sedation or anaesthesia.

A 73-year-old Chinese man was admitted to the Accident and Emergency Premorbid Ward of a local hospital in Malaysia. The patient complained of shortness of breath with cough and was in a semi-conscious state. He was later admitted to an intensive care unit (ICU) of the hospital. Six days after admission 5-6 maggots were recoverd from the nasal cavity. The maggots were identified as the third-instar larvae of Lucilia cuprina Wiedmann (Diptera: Calliphoridae) based on the morphological characteristics. This patient was classified as having nosocomial myiasis. The presence of the third instar larvae indicated that the infestation was not more than three to four days. An adult sarcophagid identified as Parasarcophaga ruficornis (Fabricius) caught in the ICU where the patient was warded provided further evidence of the potential for the nosocomial infestation.

PMID: 17547059

Many cases of myiasis have been reported in Malaysia. This is the second reported case of auricular myiasis caused by Chrysomya bezziana. The patient was a 41-year-old, mentally retarded, Orang Asli man. He was brought to the clinic by his mother with a complaint of pain and bleeding in his right ear for 3 days. On examination, blood and multiple maggots were seen packed in the external auditory canal of the right ear. A total of 39 live maggots were removed and maintained until they developed into 3rd instar larvae, which were later processed and identified as Chrysomya bezziana. The patient was discharged with amoxicillin 500 mg three times a day for 1 week.

An 88-year-old woman was brought to the hospital immediately after her neighbours noticed that she was bleeding from her right eye. On examination, her right eye was phthisic with maggot infestation of her right orbit. Over a hundred live maggots were extracted using forceps. Computed tomography scan revealed the infestation was confined to the right orbit. The patient underwent exenteration of the right orbit under general anaesthesia. The species was identified by an entomologist as Chrysomya bezziana, which has aggressive larvae that eat living tissue. This case report demonstrates that orbital myiasis caused by C. bezziana poses a very real risk of intracranial invasion as they feed on living tissues. Adjacent tissue destruction can be very rapid and definitive treatment involves urgent removal of its larvae via surgical debridement. To our knowledge, we are reporting the first case of orbital myiasis from a patient in Malaysia. Therefore, our case report may be helpful in the management of similar case of orbital myiasis.

PMID: 33973567 DOI: 10.47665/tb.38.2.031

Goat Warble Fly Infestation (GWFI) is also known as subcutaneous myiasis caused by Przhevalskiana silenus (Diptera: Oestridae). It is widely distributed in tropical and sub-tropical areas of the world. In goats, WFI is usually detected through conventional procedure which underestimated the infestation. The current study was designed to determine the serodiagonsis of GWFI (through IDEXX Hypodermosis serum antibody test) and also aimed to investigate its seroepizootiological profile in Pothwar region, Pakistan from 2013-14. The results showed that average seropositivity (ELISA kit) of GWFI was 18.5% whereas, it was 11% by using conventional procedure (Palpation method) depicting a significant difference (p<0.05). Higher seropositivity (30.8%) was observed in Jhelum district as compared to e Attock district (6%). The L1 larvae were found in September, while nodules start appearing in October to December and last until the end of February. The month wise peaks of optical density (OD) was higher in December which gradually decrease along with the end of winter season. The prevalence of GWFI revealed no significant difference among three host breeds (Jattal, Beetal and Tedy). According to the results, high infestation rate (28%) was observed in young animals of age group < 1 year as compared to old animals (> 2 years). Topographically, hilly areas (33%) provide favourable climatic conditions for the propagating of larval stages. Sex difference showed no significant difference. The seroprevalence varied significantly with respect to age, month, districts and topographical location. The current study proved that serologic diagnosis (commercial ELISA kit) as more sensitive and accurate for timely diagnosis of GWFI than traditional method. The information on the epizootiology of P. silenus in goats of Pothwar region would help in devising effective control strategies.
